There are a few things necessary when starting out on a long hike, regardless of the weather. You need a good pair of shoes, possibly boots. You need something to drink, most likely water. And finally, you need a peanut butter and pickle sandwich. Even the folks at the New York Times realize this!
If you have never made this sandwich, consider doing so in the next day or two. I don't eat it every day - in fact, the last time I did was at the top of Mt. Washington in New Hampshire. But that's primarily because I consider it a reward for trekking to the top. Go for a PB&P sandwich today, and you can just consider that a reward for finding this article.
